Listing details to confirm

The product is presented as diet whey and a meal-replacement shake, while the product details identify soy as the protein source and the ingredients also include milk protein and wheat-derived peptides. The listing states 133 servings for a 4kg tub, while directions specify 30g per serving, which would not total 4kg. Protein is given as 19g per scoop in one section and as 70% elsewhere, which do not align straightforwardly with a 30g serving. Check the pack's current nutrition panel and portion information, especially if calculating protein intake or replacing a meal.

Who is it for?

A good fit for

Adults seeking a large tub of strawberry-flavoured protein powder for post-workout or between-meal use.
Buyers who want a powder listing soy and milk protein sources alongside added fibre and other functional ingredients.

Less suited to

Anyone avoiding soy, milk, wheat or the other potential allergens named in the listing.
Buyers who need consistently smooth texture or a firmly confirmed protein amount per serving without checking the current pack details.

Customer feedback includes reports of improved lifting ability and lean muscle gains, and some customers praise the strawberry smell and macros. Others disagree on taste, mixability and protein content, with reports of grainy texture and an unpleasant consistency. That split matters for a powder intended for regular use, so buyers who are sensitive to texture may want to consider the reported variability. The overall rating distribution is more positive than negative, but it does not resolve these product-specific differences.

Positive themes

Some customers report effectiveness, including improved lifting ability or lean muscle gains.
Positive comments mention strawberry fragrance and macros.

Negative themes

Some customers report grainy texture and an unpleasant or undrinkable consistency.

Mixed feedback

Customer reactions to taste, mixability and protein content are divided.
